BOBBIN OR COP SUPPORTING MEANS FOR \VARPING-FRAMES.

Specification of Letters Patent.

Patented J an. 1%, 1915.

Original application filed October 30, 1908, Serial No. 460,238. "Divided and this application filed March 6,

To all whom it may concern:

Be it known that we, LOUIS FESSMANN and GEBHARD HAEMMERLE, the first a citizen of the Empire of Germany, the latter a citizen of the Empire of Austria, both residing at Augsburg, Germany, have invented a certain new and useful Improvement in Bobbin or Cop Supporting Means for Warping-Frames, &c., of which the following is a specification, reference being had therein to the accompanying drawings.

The invention is a division of that of our application for U. S. patent for improvements in warping frames, filed October 30, 1908, Serial No. 460,238, upon which Letters Patent No. 1,043,309 were issued under date of November 5, 1912, and comprises novel and improved means for supporting filled or loaded bobbins or cops from which the yarns or threads are tobe unwound.

The invention is capable of being employed in connection with various kinds of machines, but is designed more particularly for "use in the bobbin frames or creels of warping machines.

By the use of the invention the usual operation of winding from bobbins or cops upon spools, and the use of the ordinary creel for such spools at the time of unwinding from the spools in the warping machine are rendered unnecessary, whereby much labor is saved and much floor space is made available for other purposes.

Machines are already known wherein the warps are wound upon the beam directly from supply-bobbins or cops. Further, wheel-shaped carriers for a number of cops or bobbins have already been fitted to winding frames. However, as heretofore constructed and combined,these can only be used when the bobbins or cops and carriers can be disposed far apart, as otherwise collisions would occur between the balloon which is formed by the yarn or thread when running off. one bobbin or cop and the bobbins or cops of the next carrier, or the yarn or thread unwinding from a bobbin or cop on the latter carrier. v

The invention is illustrated in the accompanying drawings, in which latter,

porting means embodying the invention applied thereto. Fig. 2 is a sectional view of one of the combined guide, clearer, and tension-devices of Fig. 1.

Referring to the drawings,at a, a, are represented portions of horizontal rails in the form of channel-bars, and at b is an up right. The said rails a, a. in practice, extend longitudinally of the warping-frame or creel of which they form part, and are supported one above another upon the uprights b. Each of the horizontal rails or channel-bars a with the exception of the top one of. the warping-frame or creel supports a series of bobbin or cop-carriers, and each thereof, with the exception of the bottom one, supports a series of the combined guides, olearers, and tensiondevices, to which reference will presently be made. These said devices usually are termed valves or threacl-valves in the art.

Each cop-carrier comprises a base 0 and a series of bobbin or cop-receiving spindles f. The said spindles are hinged or pivoted between pairs of upstanding lugs e on said base, so that a spindle may be swung downward and outward, as represented at the right-hand side in Fig. 1, into position to enable an empty bobbin or cop-tube to be removed therefrom and a full bobbin or cop to the applied thereto. without interfering with the other bobbins or cops, and, what is more important, without interfering with the unwinding yarn or thread as it circles about its bobbin or cop. This capacity of the respective spindles to be swung outward for the purpose of supplying fresh bobbins or cops enables the bobbins or cops to be set more closely together upon the carrier, and to converge much more closely together at their upper ends, than would be possible otherwise. It enables the bobbins or cops to be brought more nearly in line with a line passing down through the center of the delivery-guide above them, and renders it possible to locate the said guide at a very short distance above the upper ends of the bobbins or cops. Thereby the extent of the ballooning of the unwinding yarn or thread as it circles around the bobbin or cop from which it is being drawn is very much reduced, which not only reduces the liability to breaking of such yarn or thread, but enables the carriers to be set closer to one another, thereby reducing the size of the bobbin or cop -supporting frame and consequently the extent of floor space that is occupied.

The base a of each cop-carrier rests upon the upper surface of the supporting rail or channel-bar a therefor, and is secured in place by means of a bushing t having a flanged lower end, the stem of such bushing being extended up through a hole in the base a as shown in Fig. 2, the screw-threaded portion of the said stem having applied thereto the nuts u and 12 between which and the upper surface of the rail or channel-bar the base 0 is clam ed.

When the bobbins or cops are placed on the spindles f a little yarn or thread is unwound from each bobbin or cop, and the inner end of the yarn or thread of one bobbin or cop is connected to the outer end of the yarn or thread of the neXt bobbin or cop and so on throughout the group. Consequently when the yarn or thread of one bobbin or cop becomes completely unwound, the unwinding will continue immediately from the next bobbin or cop in turn, and so that fresh bobbins or cops may be supplied as soon as the previous ones have become exhausted, the unwinding operation thereby proceeding continuously and without interruption. Thereby the waste portions of yarn, which in the case of other methods of unwinding have had to be left unwound, and which have added unnecessary weight of material, with increase of cost and loss of value, are obviated. 011 its way to be wound, the yarn or thread passes through the combined guide, clearer, and tension-device which is located immediately above the upper ends of the bobbins or cops upon the spindles f, and is cleared as it passes therethrough so that when wound it is perfectly clean and at the necessary tension. The said combined guide, clearer, and tensiondevice is mounted upon the rail or channelbar a next above that on which the cop-can rier is mounted. It comprises essentially a seat or guide p in the form of a ring, and a plate or disk m which rests upon the top of the said ring. The yarn or thread unwinding from one of the bobbins or cops on the carrier below passes up through the bore 0 of the ring 79 and then turns, passing outward between the ring and plate or disk. The latter rests by gravity upon the yarn, the friction due to the passage of the yarn through the bore 0 of the ring, and to the bending of the yarn or thread nearly at right angles over the ring, as well as to the passage of the yarn or thread between the surfaces of the ring and the plate or disk, imparting the required tension to the yarn or thread. As the yarn or thread passes through the device, loose particles are detached therefrom, the bore 0 of the ring permitting the said particles to fall away. The plate or disk m is connected loosely with the lower end of a stem or pin Z, which occupies the central bore of the bushing and is movable vertically therein. This provides for confining the said plate or disk in proper Working position, while leaving it free to be raised by an operative as the latter introduces the yarn or thread between it and the top of the ring, and also free to descend by gravity so as to rest upon the top of the ring and the yarn or thread, and 1n addition permits it to accommodate itself to variations in the thickness of the yarn or thread, or knots or loops.

The escape of loose material which may be detached at the combined guide, etc., and which might tend to clog the device and prevent the plate or disk m from closing and acting properly, is provided for by means of a slide-bar which is mounted upon one side of the rail or channel-bar by which the combined guide, etc., is supported, by means of screws 70, 7c, the stems of which occupy slots 76 is, formed in the slide-bar and extending longitudinally of the latter. The slide-bar is formed or provided with an upwardly projecting nose or cam-portion 2' adjacent each combined guide, etc. The slidebar 70 is connected in practice with means whereby it automatically is moved back and forth every few seconds. This reciprocating movement causes the nose or cam-portion i to pass back and forth beneath a pin 1' projecting horizontally from the upright stem or pin Z out through a vertical slot in the rail or channel-bar and extending over the upper edge of the slide-bar. Each time the nose or cam-portion 2' passes under and past the pin 1', it raises the latter and the stem or pin Z and plate or disk m, and then leaves them free to descend by gravity again. By this means the disk m is raised sharply at intervals so that loose particles fall out and the thread runs on again under the correct tension.' The ring 79 has an oblique slot at for admitting the thread into its bore 0, and preferably is constructed of glass, as also are the other .parts used solely for guiding the thread. The ring 32 is held in a hook-shaped supporting piece 5 and can easily be removed and replaced by hand. The bushing t passes through a hole in the upper part of the supporting piece 8, and the latter is clamped by the flange of said bushing to the rail or channel-bar to which the bushing is applied.
